The need for Pipeline Optimisation

By Jonathan Theakston, Operations Director (Simulation Software Limited)

Published in the September edition of World Pipelines Magazine, 2016

Abstract

Many pipeline operating companies are focusing on optimising the performance of their pipelines and the focus is not only driven by a desire to maximise the financial return from the pipeline asset, it is also driven by a desire to be safer, greener and more ethical. If a pipeline can be optimised to minimise its energy usage, it follows that the operating costs and the greenhouse gas emissions will also reduce.

Pressure Safety Valves for Heat Exchanger Tube Rupture
High Pressure Protection

By Glyn Addicott, Operations Director (Hydraulic Analysis Limited)

This paper on our work was presented at the 3rd Hazards Asia Pacific Symposium in Kuala Lumpur in April 2015.

Abstract

A Shell & Tube Heat Exchanger Overpressure Protection Joint Industry Project (STHE JIP) was undertaken and managed by the Energy Institute (EI). HAL were involved with the dynamic simulation section of the JIP on the Steering Committee. The key deliverable of the STHE JIP was to look at alternatives to burst discs for heat exchanger high pressure protection. The work undertaken by HAL considered the use of spring relief and pin valves for high pressure protection and the published guidelines cover this new development. The modelling included calibrating the response and capacity of different relief devices by interpreting the performance testing which was undertaken by the University of Sheffield.

We modelled the impact of fast transient tube ruptures on various STHE design geometries, and assessed the impact of the pressure wave in the adjoining pipework. This ensured consideration for overpressure of the low pressure side, connecting piping and the effects upstream and downstream of the exchanger in the low pressure piping system where the tube failure occurred.

Fully interactive pipeline simulation.
Go beyond the liquid parts and apply control schemes

By Jonathan Theakston, Operations Director and Nick Jansen, Software Director (Simulation Software Limited)

Presented at the Pressure Surges Conference in Edinburgh (14th – 16th May 2008)

Abstract

The hydraulic behaviour of an operating pipeline is primarily influenced by the characteristics of the fluid, the pipe work and the operating equipment installed on it. Simulation of this hydraulic behaviour has been attainable now for many years and simulators have been instrumental in supporting the design and planning processes of fluid pipelines and networks. However, the equipment installed on a modern pipeline is increasingly controlled by both local control logic and SCADA systems. If the simulators are to remain accurate and have maximised value, they must be supplemented with control logic that accurately models complete pipeline control schemes.

The Next Generation of Network Management and Leakage Systems

By Glyn Addicott, Operations Director (Hydraulic Analysis Limited)

This paper was presented at the 2016 South West AWWA Conference in Rogers, Arkansas in October 2016 and discusses water distribution network management and transient real time simulators which identify leaks, extend pipeline life expectancy and reduce the risk of bursts.

Abstract

The Hydraulic Analysis Group have taken their knowledge in surge analysis and pipeline transient operation to develop the next generation of water distribution network management and leakage systems by using real time data to create real time simulators.
